Abstract

The invention relates to the technical field of optical communication, and provides an optical fiber adapter structure. The optical fiber adapter structure comprises a metal flange 101, a tube body 102, an insulating ring 103, an optical fiber inserting pin 104, and a shielding ring 108. The optical fiber inserting pin 104 is embedded into the metal flange 101. The shielding ring 108 is fixed at the bottom of the metal flange 101 through a conductive adhesive 107. The shielding ring 108 covers the end part of the inserting pin 104, and is provided with a reserved hole used for allowing only laser signals to pass through. The tube body 102 is connected with the bottom of the metal flange 101 in a sleeved mode. The insulation effect is achieved between the tube body 102 and the metal flange101 through the insulating ring 103. According to the invention, the shielding ring 108 made of conductive materials is adhered to the tail end of the metal flange 101 through the conductive adhesive107, and the complete electrical contact is maintained. The electromagnetic wave radiation between the interior of the optical device and the outside of the metal flange 101 is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of optical communication, in particular to an optical fiber adapter structure. 【Background technique】 [0002] Optical fiber communication systems are developing towards high speed and high port density. As one of the core components of optical fiber communication, optical devices are also facing these technical challenges. The more compact etc. [0003] At present, the frequency of signals processed by high-speed optical devices has reached 25 GHz, and the electromagnetic compatibility problems caused by high-frequency signals are very serious. In order to improve the influence of electromagnetic compatibility problems, optical fiber communication systems, high-speed optical modules, and optical devices usually use metal materials as housings, and at the same time minimize the gaps between housing components. Partially strengthen electromagnetic shielding and other means, and at the same time reduce the...
